A phase-field model is proposed to simulate coherency loss coupled with microstructure evolution.A special field variable is employed to describe the degree of coherency loss of each particle and its evolution is governed by a Ginzburg-Landau type kinetic *** the sake of computational efficiency,a flood-fill algorithm is introduced that can drastically reduce the required number of field variables,which allows the model to efficiently simulate a large number of particles sufficient for characterizing their statistical features during Ostwald *** model can incorporate size dependence of coherency loss,metastability of coherent particles,and effectively incorporate the underlying mechanisms of coherency loss by introducing a so-called differential energy *** model is applied to simulate coarsening of Al3Sc precipitates in aluminum alloy and comprehensively compared with *** results clearly show how the particle size distribution is changed during coherency loss and affects the coarsening rate.

The discovery of the essential difference of maximum ion energy for TW-pslaser plasma interaction compared with, the 100 ns laser pulses led to the theory of a skin layermodel where the control of prepulses suppressed the usual relativistic self-focusing. The subsequentgeneration of two nonlinear force driven blocks has been demonstrated experimentally and inextensive numerical studies where one block moves against the laser light and the other block intothe irradiated target. These blocks of nearly solid state density DT plasma correspond to ion beamcurrent densities exceeding 10^(10) A/cm^2 where the ion velocity can be chosen up to highlyrelativistic values. Using the results of the expected ignition of DT fuel by light ion beams, aself-sustained fusion reaction front may be generated even into uncompressed solid DT fuel similarto the Nuckolls-Wood scheme where 10 kJ laser pulses produce 100 MJ fusion energy. This new andsimplified scheme of laser-ICF needs and optimisation of the involved parameters.

In this work, enhancement of the light extraction efficiency of a 590 nm AIGaInP light-emitting diodes （led） with a reflective top electrode （RTE） was investigated. A distributed Bragg reflector （DBR）, consisting of AIAs/AIGaAs pairs, grown on an AlGaInP structure was used as a reflector for a reflective top electrode. It was found that a higher output power was observed from the AIGalnP led with a RTE than from a conventional one. In addition, it was noted that the improvement in the output power depends strongly on the reflectivity of the reflector and that it exhibits a more effective performance with low injection currents. The increase in the optical output power was attributed to the enhanced extraction efficiency caused by a reduction of light absorbed from the emission region to top electrode through the RTE.
